SPECIFICATION formingpart of Letters Patent No. 629,485, dated July 25, 1899.

Application filed May 15, 1899. Serial No. 716,790. (No model.)

To (tZZ whom it may concern:

Be it known that I, TALBOT O. BATEMAN, a citizen of the United States, residing at Fort Worth, Texas, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

This invention relates to apparatus for the production and storing of acetylene gas; and the object is to construct a machine which will be compact in form and simple in construction and perfectly automatic in operation and in which the generating-chamber, the water-supply-tank, the storage-chamber for gas, and a plurality of-cups for storing carbid will all be contained in one small vessel cylindrical in form.

Other objects and advantages will be fully explained in the following description and more particularly pointed out in the claims.

Reference is had to the accompanying drawings, which form a part of this application.

Figure 1 is a vertical section of the storagechambers and the generating-chamber. Fig. 2 is a plan View of the machine. Fig. 3 illustrates the arrangement and construction of the carbid-cups, the View being a broken sectional view. Fig. 4 is a detail view of the chute for feeding water to the cups. Fig. 5 is a detail View of the casting which holds the generating-chambers in place. Fig. 6 is a front view of the gage for determining the amount of gas in the storage-chamber.

Similar characters of reference are used to indicate the same parts throughout the several views.

The water compartment A is mounted above the gas-storage chamber'B and is provided with an orifice a and cap b. A tube O forms a passage from the upper chamber A to the lower chamber B. This tube is provided with a cut-off valve 61-, which is operated by the rod g, which projects up through the top of chamber A and is provided with a handle f. One or inore-.generating-chambers D are mounted in chamber B. The chamber D is cylindrical in form and has an annular flange h at the top, which flange rests on an interior annular flange k of a casting G. The casting G has a shoulder m on the outside, Which forms a joint against thetop n of the chamber A. The casting is soldered taken out of the chamber.

air and gas tight to the top a of the chamber A. A gasket-ring p is placed on top of the casting G, and a cap F is screwed on the casting for closing the passage through the casting. Cap F is provided with a handle with several small holesj for gas to pass to the storage-chamber B. A small chute H for a Water-drip is pivotally attached to the interior of the chamber D. The chute is adapted to cause the water to drop in the center of the carbid-cup and is pivoted so that it will not obstruct the passage of the cups when being The chute II is made and set so that it will yield upward, but There are several of these cups J, and all are locked together, so that all may be taken out together. Each cup is closed at the bottom and has a chime N at the top with holes M therethrough and a chime P at the bottom with holes M therethrough. Thechime P of one cup rests within the chime N of the next cup below. The holes M and M are so made that they are in alinement with each other and serve a double purpose. They let the gas escape from the cups, and they are so made that the pipe K will pass through both chimes, and thus lock the cups together. The pipes K serve a double purpose. They serve to convey water to the next cup below and to lock the cups together. These pipes rest in the perforations M M and may be rigid or flexible. It will be observed that the cups are so arranged that all the carbid in the cup above will be used up, and when the water overflows it will go to the next cup below, and so on until the last cup in the generatingchamber is reached. \Vater enters through a small opening just above the water-drip. After the carbid is used up out of one gener- The generating-chambers D are provided ating-chamberthe water will run into anwater-drip H is attached to the interior of the chamber by attaching, by soldering or otherwise, a piece of E-shaped metal H and then pivoting the drip Hin this piece'of metal. Compartment B is provided with a draincock It and a gas-pipe R for conveying away the gas for consumption. Means are provided for closing the opening through the casting G when agenerating-chamberis taken out. The casting has two lugs a projecting downward, to which is hinged a cap E by means of the lug 1). Cap E is lined with some elastic packing E. hen one of the chambers D is taken out, the cap E will be pressed against the openingin the casting G by means of a spring E, which is attached to the top of the compartment B. A gage V is provided for showing the pressure of the gas. A weight V is attached to the gage by means of a cord V", which runs over a pulley w and is wound on the usual spring-dru1n of the gage.

The operation may be described as follows: The carbid is placed in the cups J, and the cups are placed in the generating-chambers D. Water is poured in the compartment B through the openings in the castings G, enough water being put in to come just above the opening '1' in the generating-chamber after the chamber is put in place. The chamher having the opening 0' lowest down is the one to be observed in putting in a supply of water. More water can be added after the carbid in the first chamber is used. When the gencrating-chambers have been put in place, the caps F are screwed down gas-tight on the gasket-rings. Gas will commence to generate as soon as water commences to run on the carbid and escape through the openingsj and collect in compartment B and force water up through tube G into compartment A. The pressure of the gas will soon force the water below the opening 0', so that too much water will not run on the carbid. Care must be taken to keep the cock cl open while gas is being generated. The chamber or compartmentA must not be air-tight. The openings for the rods g and V" will be suiiicient for the escape of air when the .gas in compartment B forces water up into compartment A. This provision will prevent any danger of explosion. If the pressure of gas becomes great enough to force the water below the mouth of tube 0, the gas will escape through the tube 0 and out of chamber A. The amount of pressure can be determined by the gage V.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

posed before the water overflows to the next cup below and the gas will escape and be collected in said compartment for use.
